PCB NC Battery Charge

Charging Circuit for the NC Battery

Revision D
Functional Description: PCB NC Battery Charge
The MAC 1200 resting ECG analysis system can operate on battery power. With a
new, fully charged NC battery, up to 50 ECGs can be recorded in Automatic (12-
lead) mode.
The PCB NC battery charge controls and monitors the charging process, depending
on the status of the battery and the status of the device.
An integrated charging device is used to charge the battery. During charging, it
monitors the battery voltage function and switches over from rapid charging to
trickle charging.
Applying the line power to the MAC 1200 resting ECG analysis system, or
insertion of the battery activates the charging circuit. During a recording, the
charging current is reduced. In standby mode, a depleted battery is fully charged
within 4 hours.
